I managed to get into the telnet via a Linux emulator on my Chromebook which showed immediately on the console as a Switch, which is unusual. I copied and upgraded as per the instructions but it failed to reboot at stage 20 (08080hufi) so I had to downgrade again.
Interestingly, the system works fine with 08080f on secondary but will not boot with 08080d on primary. I even tried to copy the secondary to the primary but it keeps showing as 08080d.n Could it be that my primary flash has corrupted?
I also can still not access the switch via the GUI. Even though I can log into the App which I’m guessing is the same credentials.
